SPECIFICATION forming part of; Letters Patent No. 278,508, dated May .29, 1883.

Application filed March 19, 1 882. (N modeLi To all whom it may concern:

Be it known that I, CHARLES WARREN.

CHENEY, a citizenof the United States,iresiding at Athol, in the county of Worcester andStat-e-of Massachusetts, have invented certainnew and useful Improvements in Mowlng-M'achin'es; andI do herebydeclare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same- My invention relates to certain new and useful improvements in mowing-machines, and more particularly to the class employing two reciprocating cutters moving in opposite directions to co-operate, like shears, in severing the blades of grass. A

The object of my invention is to simplify the construction of the several operating parts of the above-described class of machines, while at the same time rendering them more durable and eflectualin operation.

The invention therefore consists in novel features of constructionand combination and arrangement of parts, all as will be hereinafter fullydescribed, and setforth in the claims here to annexed. H i

Referring to the accompanying drawings, Figure 1 is a plan ortop viewof my improved machine; Fig. 2, abottom plan Fig. 3, a vertical transverse section; Fig. 4, a vertical longitudinal section; Fig. 5, afront elevation; Figs.6, 7, and 8, detail views.

In the drawings, A represents the frame of the machine; B B, the supporting and drive wheels, provided with the usual clutch mechanisin for connecting .them with the shaft 0,

which is j ournaled in bearin gs or boxes b b,c0n-

nected or secured to the frame of themachine.

Upon the shaft 0 is loosely mounted the cam disk or wheel D,-adapted to be connected or thrown into'gear with said. shaft Othrough themedium of the usual clutch mechanism, 0 d. The cam disk or wheel I) has a doublegrooved rim, d, the grooves and projections d? d on one side of said rim (1 alternating with the corresponding grooves and projections on the other side thereof, all as clearly shown in Fig. 1, so that the centers of the grooves on one side of the rim are directly opposite to or on right lines with the centers of the projections on the other side of the rim;

screw, 6. The arm- E has a rear forked end,

F,trigidly secured thereto or formed integral therewith, as shown in Fig. 7, so as-to embrace or extend on opposite sides'of the grooved rim of the cam wheel D, the forked endsff having on their sides-recesses ff. in which are ar- 3 ranged anti-friction rolls f f, mounted on journalsf f and adapted to engage, with the double-grooved rim of the cam-wheel D. The

object of having the arm E adjustably secured in the shaft Gris to permit its being drawn for ward to replace the anti-friction rolls when,

, worn, or for other purposes that may be deemed expedient in repairing the operating parts of the machine.

To the lower end of the shaft G is rigidly and centrally secured, or formed integral therewith, a transverse, bar, 9, connected at itsends by links 9 g with the outer ends of oscillating bars H H,journaled to the under side of the frame A, with one bar in advance or in front of the other, as shown in Fig. 2, the fulcra .of said barsbeing'one-third of their lengths from their-outer ends.

I I represent substantiallytransverse parallel rods connecting the inner ends of the bars H Hwith the inner" ends of the cutters J J, adapted to work in the usual finger-bar, K,

rigidly connected to the forward end of the usual rocking shoe, k.

double compound connection between the shaft G and cutters J J, so that an alternating reciprocating movement is given to the cutters thatwill pass the teeth beyond each other.

L represents the usual lever, connected to the inner end of the linger-bar by a chain, 1, for lifting'or raising the outer'end of the finger-bar. As heretofore employed, an independent'lifting-leverhas generally been necessary, in order to raise the inner end of the finger-bar and shoe in passing over obstructions. I accomplish the same result through the medium of the lever L and the followingdeseribcd friction-connection:

M represents a vertical bar loosely or pivotally connected at its lower end to the shoe It,

and which has a free vertical movement between the inner side of the bar aof the frame A and the guide-plate m, secured thereto. Said bar M is'held in a rigid position, when it is necessary to raise only the outer end, of the fin ger-bar, by-means of a pivoted lever, N, having its fulcrum on the projecting rear end of the plate a, so arranged that when the longer arm'n of the lever N is pushed forward by the foot of the operator the shorter end of said lever will press against the bar M, and hold it from vertical movement by the frictional contact of the bar with the rear side of the beam 0 or plate m, or a shoulder thereon, the lever N being secured in position by en gaging the ratchet-bar M.

The shoe It extends rearwardly, forming the push bar, which is connected in the usual manner to the rear of the frame A by a ball-andsocket joint, and upon said push-baris mounted a sleeve, 0, having an arm, said sleeve bein g ad j ustably secured thereon by a set-screw, 0. The arm of this sleeve 0 is connected to the shipper-bar]? by a link, 0, so that in raising the outer end of the finger-bar the shoe and push-bar will be turned or oscillated, and thereby disconnect the clutch mechanism, which will be again thrown into gear when the finger-bar is lowered by the shoe and push-bar oscillatingorturningback to their original position. By the above-described arrangement I am enabled to throw the operating mechanism in and out of gear through the movement of the lifting-lever, which raises the finger-bar, andsimultaneously therewith.

The mechanism for raising and lowering the finger-bar and throwing the operating mechanism in and out of gear is applicable to other forms of mowing and reaping machines, and hence I-do not desire to limitmyself to its use in the class of machineshereinbeforedescribed.

The cam-wheel as constructed in connection with the means for connecting it with the cutters, as before described, while simplifying the construction, is effectual in operation.

The operation of the machine is deemed obvious from theforegoing description. The machine being drawn over the surface of a field 0r plat of grass, movement is communicated through the supporting or drive wheels to the shaft and cam-wheel, and thence to the cutters through the medium of the intermediate connecting mechanism, by which they are reciprocated or vibrated in opposite directions, which causes them to cooperate, like shears, in severing the blades of grass.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-a 1. The combination, in a mowing-machine, of the cam-wheel having grooves and projections alternating with each other on opposite sides of its rim, the forked arm E, provided with the anti-friction rollers, the vertical shaft v G, transverse bar g, links g g, pivoted bars H H, parallel transverse rods I I, cutters J J, and finger-bar, substantially as and for the purpose herein shown and described.

2. In a mowing-machine, the combination, with the cutter or cutters and operating mechanism, the finger-bar, lifting-lever, shoe, and

push-bar, and the clutch mechanism, of the adjustable sleeve and link 0, for connecting the push-bar with said clutch mechanism, whereby in raising the finger-bar through the medium of the lifting-lever the cutter mech anism will be simultaneously thrown out of gear, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES WARREN CHENEY.
